Just thought I'd throw this at ya. It's two authors sharing their writing experiences and how-to's. Their writing style is very different from Jim Butcher's from his livejournal. But they have interesting things to say about character flaws and character development, etc. So take what you need and leave the rest. Hope it's helpful. They're taking down the site at the end of the year to write their own How To book. Every little bit helps.
